✨AI Revenue EstimateCONFIDENCE: HIGH
The TK-App by Techniker Krankenkasse (TK) is a service application for its members, offering features like submitting documents, managing bonus programs, and accessing health records. As a statutory health insurance provider in Germany, TK's revenue comes from member contributions, not from direct in-app purchases or subscriptions within the TK-App. Therefore, the app itself does not generate direct revenue.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
